This came to mind after completing Extraordinary You yesterday.
I finished it, updated my list to reflect that, and have been periodically checking the comments on the page to see what other users thought of it... and I'm forced to reveal every single spoiler each time I go back to the page. Once we have completed a drama or movie there is nothing left to spoil.
I don't know if this feature could be implemented or if it's completely useless, however, I personally think it could be a nice addition at some point down the road.
